The first motion assembly is connected to the driving device to drive the first positioning frame 15 to move relative to the second positioning frame 20 under the drive of the driving device and drive the cutter roller installed on the installation component to rotate.

[0026] Combined with Figures 1 to 2As shown, in this embodiment, a space suitable for accommodating the quenching rack 13 is formed inside the quenching tank 1 for quenching the cutter roller on the quenching rack 13. An opening is formed on the quenching tank 1, and a liftable and movable protective plate 2 is provided at the opening. The protective plate 2 is used to open or close. When opened, it is suitable for the quenching rack 13 to enter and exit. When closed, it is suitable for closing the quenching tank 1 to keep a certain airtightness inside the quenching tank 1. A guide rail 3 extends inside the quenching tank 1. A bottom plate 4 is connected to the guide rail 3 through a pulley 5. The quenching rack 13 is suitable for being installed on the bottom plate 4. Through the movement of the pulley 5 on the guide rail 3, the quenching rack 13 can conveniently enter and exit the quenching tank 1. A fixed seat 6 is further provided on the bottom plate 4. The fixed seat 6 is used to cooperate with the bottom surface of the protective plate 2, so that when the protective plate 2 descends, the inside of the quenching tank 1 has better airtightness. Further, the lifting device includes a second motor 7 provided on the quenching tank 1. The second motor 7 is connected to a lead screw 8. The lead screw 8 is connected to the protective plate 2 through a lifting seat 9. Positioning ridges 12 are extended and provided on both sides of the protective plate 2, and positioning grooves 11 matching the positioning ridges 12 are provided on both sides of the quenching tank 1, so that the protective plate 2 can slide in the positioning grooves 11 through the positioning ridges 12. Here, the second motor 7 can be fixed through a lifting frame 10. The second motor 7 drives the vertically arranged lead screw 8 to rotate to drive the protective plate 2 to perform a lifting movement.

[0027] Combined with Figure 3As shown, the quenching rack 13 includes a positioning device 14 and a driving device. Here, the driving device is the first motor 21, which can rotate forward and backward. The positioning device 14 is fixed by two positioning frames 34 arranged on the bottom plate 4. It includes a first positioning frame 15, a second positioning frame 20, a first motion component and a second motion component. Among them, the first positioning frame 15 and the second positioning frame 20 have the same shape, are arranged in a square shape, and are arranged vertically. A second motion component is arranged between the first positioning frame 15 and the second positioning frame 20. Both ends of the first positioning frame 15 and the second positioning frame 20 close to the positioning frame 34 extend outwards and are each provided with two first fixing rods 16. The first fixing rods 16 on the two positioning frames correspond up and down. And on the bottom surface of the first fixing rod 16 of the first positioning frame 15 and the top surface of the first fixing rod 16 of the second positioning frame 20, first racks 17 are both provided. A first gear 18 is meshed and connected between the two opposite first racks 17. Further, two of the first gears 18 are arranged at both ends of the first positioning frame 15 and the second positioning frame 20, and the two first gears 18 at the same end are connected by a positioning shaft 19. One of the first gears 18 is drivingly connected to the first motor 21. When the first motor 21 rotates, it can drive the first gear 18 to rotate. Through the action of the gear and rack, it drives the first positioning frame 15 and the second positioning frame 20 to generate relative motion, and further drives the second motion component to rotate. In this embodiment, a positioning seat 22 is arranged on the positioning frame 34. A through hole is horizontally arranged on the positioning seat 22. On both sides of the first positioning frame 15 and the second positioning frame 20, first positioning rods 23 adapted to pass through the through hole are arranged. A first limiting block 24 is arranged at the end of the first positioning rod 23. By passing the first positioning rod 23 through the positioning seat 22, the first positioning frame 15 and the second positioning frame 20 are kept on the positioning frame 34, and the first positioning rod 23 plays a guiding role.

[0028] Continue to combine Figure 3 and Figure 5As shown, the second moving component includes second racks 25 disposed on the bottom surface of the first positioning frame 15 and on the top surface of the second positioning frame 20. Specifically, the second racks 25 are disposed on the long sides of the first positioning frame 15 and the second positioning frame 20, and the second racks 25 are provided on two opposite long sides. A plurality of second gears 26 are meshed between the second racks 25. When the first positioning frame 15 moves relative to the second positioning frame 20, the second gears 26 also rotate, thereby driving the mounting component and the cutter roller fixed on the second gears 26 to rotate. Here, the mounting component includes a first positioning ring 27 and a second positioning ring 28 fixed on one side of the second gear 26. The first positioning ring 27 and the second positioning ring 28 enclose an adjustable mounting hole suitable for mounting the cutter roller. The first positioning ring 27 and the second positioning ring 28 are provided with mating protruding ears 29, and adjustment holes are provided on the protruding ears 29. A second positioning rod 30 for connecting the first positioning ring 27 and the second positioning ring 28 is inserted into the adjustment holes. Here, two protruding ears 29 are provided on each positioning ring and are mating. Two adjustment holes are formed on each of the protruding ears 29. The second positioning rod 30 is inserted into the adjustment holes, and a second limit block 31 is formed at the end of the second positioning rod 30 to prevent the second positioning rod 30 from coming out. An elastic member 32 is further disposed in the second positioning rod 30. The elastic member 32 is disposed between the second limit block 31 and the protruding ear 29, so that there is a certain elasticity between the first positioning ring 27 and the second positioning ring 28. During use, the first positioning ring 27 is pulled to increase the distance between it and the second positioning ring 28, so that the cutter roller can be conveniently placed. After placing, the first positioning ring 27 is released, and the first positioning ring 27 is reset by the elastic recovery of the elastic member 32 and presses the cutter roller. Here, the second positioning ring 28 can be directly fixed on the second gear 26, and the first positioning ring 27 is connected to the second positioning ring 28 through the second positioning rod 30. The elastic member 32 can be a spring. Further, anti-slip pads 33 are provided on the inner sides of the first positioning ring 27 and the second positioning ring 28 to prevent the cutter roller from sliding.

[0029] In this embodiment, a switch panel (not shown) is fixedly provided on one side of the quenching tank 1. A first motor 21 switch and a second motor 7 switch are respectively fixedly provided on the surface of the switch panel. The first motor 21 and the second motor 7 are respectively electrically connected to an external power supply through the first motor 21 switch and the second motor 7 switch, so as to facilitate control.

[0030] During operation, all the cutter rollers are installed on the installation component. The lifting device is used to control the lifting of the protective plate 2 to open the quenching tank 1. The quenching rack 13 is pushed into the quenching tank 1 along the guide rail 3. Then, the lifting device is controlled to lower the protective plate 2 so that the bottom of the protective plate 2 abuts against the bottom plate 4 to close the quenching tank 1. Next, the rotation of the cutter rollers is controlled by controlling the rotation of the driving device, enabling the cutter rollers to be turned over during quenching, facilitating all-round quenching, and simultaneously enabling multiple cutter rollers to be quenched at one time.
